Two dogs were killed after they attacked a police officer responding to a home alarm on Tuesday, New Castle County Police said.

Police were responding to an alarm at a home on the unit block of Bunche Boulevard near New Castle around noon. An officer entered the home's rear yard and was attacked by two dogs that police said resembled pit bull terriers.

The officer unsuccessfully tried to use a taser on one dog before fatally shooting the animal. The other dog "remained aggressive" when located on a nearby block and was killed, police said.
